Well I have seen many times we bulgarians are grouped with greeks, italians and other southern europeans, I believe there are many similiraties but differences are bigger. I have also seen people tell me we're  not slavs. that confuses me because bulgarians identify themselves with slavs, exception are small minority who think they are iranians :D
I am also trying to be objective posting pictures of crowds and big groups only. I can cherry pick blondes only but there is no point in this. There are probably non bulgarians on some pics, but its impossible to avoid them, because minorities (turks, gypsies armenians jews) more than 20% of our population
